Method of making an organic thin film transistor and article made by the method
EP 0825657 A3
Abstract
Thin film transistors in which the active layer is an ordered film of a pthalocyanine coordination compound with a field-effect mobility greater than 10-3 cm2/Vs and a conductivity in the range of about 10-9 S/cm to about 10-7 S/cm at 20C are disclosed. Examples of suitable pthalocyanines include copper pthalocyanine, zinc pthalocyanine, hydrogen pthalocyanine, and tin pthalocyanine. Thin film devices made of these materials have an on/off ratio of at least about 104. It is advantageous if the device is fabricated using a process in which the substrate is heated to a temperature in the range of about 30C to about 200C when the film is formed thereon.
